I worked with Staci Elaan to build this hammer that has a solid state tesla coil inside. When you push the button, 80,000 volts of electricity arc from the top.

It will light up any flourescent bulbs around, scare children, and leave the smell of ozone behind. It is super fun!

Still a prop, but a very cool prop. And with that, my friends, I send you off into the weekend. Feel free to talk about whatever you'd like, either here in this open thread or over in the spiffy Talk Amongst Yourselves.
